<P>PROBLEM TO BE SOLVED: To improve workability and convenience in a system wherein an ion exchange resin is used as an impurity removal means in an off-gas circulation line. <P>SOLUTION: This fuel cell system is provided with: a fuel cell 2 for generating power by an electrochemical reaction of a reaction gas; a gas supply passage 22 for supplying the reaction gas to the fuel cell 2; the off-gas circulation line 23 for circulating an off-gas after reaction in the fuel cell 2 to the gas supply passage 22; and the impurity removal means 30 arranged in the off-gas circulation line 23; wherein the off-gas circulation line 23 is filled with the ion exchange resin 32. The fuel cell system is also provided with: a regenerant for regenerating the ion exchange resin 32; and a regenerant tank 34 and a regenerant supply line 35 for supplying the regenerant. <P>COPYRIGHT: (C)2008,JPO&INPIT |
